Description
GUMMI A-350/350 is a flexible coupling reference, within Power transmission. Request a quote for A-350/350 via WhatsApp or email with the quantity you need; we respond promptly with lead time and equivalents.
The GUMMI A-350/350 flexible coupling is a power transmission component that joins two shafts and absorbs misalignment, vibration and torque peaks through an elastic rubber center. It is used in heavy drives where continuity of operation and machine protection are needed. MR Accesorios Industriales sells it in Buenos Aires, Argentina, and advises you on choosing the correct configuration for your application.
This coupling from the Type A series, model A-350/350, has a configuration of two standard hubs (CN) and an elastic rubber center. The nominal torque is 118750 Nm, with a maximum bore of 350 mm and a pilot bore of 120 mm. The diameter of the elastic center is 1130 mm, the total length is 1085 mm and the weight is 2237 kg. These are catalog values that define its capacity and dimensions for assembly.
It is used in high-power transmissions: mills, crushers, large centrifugal pumps, industrial fans, conveyor belts and marine or mining drives. The rubber center allows a certain angular and radial misalignment, dampens torsional vibrations and prevents load shocks from passing directly to the gearbox or motor. It is a robust solution for continuous service in demanding environments.
To select it, verify the nominal torque and starting peaks of your equipment, the shaft diameter and the available length between ends. The CN configuration allows mounting with two standard hubs; if you need another arrangement, ask us. The maximum bore of 350 mm and the pilot bore of 120 mm guide the machining. Check alignment before tightening and follow the manufacturer's instructions for bolt torque.

Frequently Asked Questions
- What does the CN configuration mean on the GUMMI A-350/350 coupling?
- CN indicates two standard hubs, meaning both ends of the coupling have standard hubs to mount on the shafts. This configuration is the most common in transmissions where both shafts are of the same type and simplicity of assembly and replacement is sought.
- Can I replace an old coupling with this model?
- Yes, if the nominal torque, shaft diameters and length between ends match. Send the part number of the original coupling and your shaft dimensions via WhatsApp; we verify the equivalence with the A-350/350 or with another variant of the Type A series.
- How do I request a quote for the GUMMI A-350/350 coupling?
- Write to us on WhatsApp with the part number A-350/350 and the quantity you need. If you have doubts about the configuration or the bore, also send the data for your equipment. We will reply shortly with the technical and commercial information.
